Once a Traffic Control Device (TTCD) is deemed unacceptable, how many hours do you have to remove or replace it after notification?

When a Traffic Control Device (TCD) is considered unacceptable, a prompt response is essential to maintaining safe traffic conditions. The requirement to remove or replace the device within 12 hours of notification reflects a commitment to upholding safety standards and minimizing risks to both roadway users and work zone personnel.

Timely action is crucial because an unacceptable TCD can create confusion, lead to unsafe driving conditions, or fail to effectively manage traffic flow. The 12-hour timeframe allows for a reasonable yet urgent response to address the issue, ensuring that any safety impacts are mitigated quickly.

The other options suggest longer response times, which would not be as effective in ensuring the safety and efficiency of traffic management in work zones. By adhering to the 12-hour requirement, organizations demonstrate diligence in traffic safety protocols, enabling a more responsive approach to any potential hazards presented by defective or improper traffic control devices.
